I had been saving calories so that I could eat fast food today. I went and had it for lunch, and got a MAJOR headache afterwards. I don't know if it was the sodium, or what (I don't have high blood pressure or anything). Then I remembered how often I would get headaches before I started eating right, like I'd probably go through 50 tablets of Advil a month. I was thinking about going to the doctor, because it seemed like I always had one, and then when I changed my eating they disappeared. I really didn't notice they had stopped until today when I got one.
Never say never, but I will say if I ever eat fast food again it won't be for a looooong time. It was yummy, but not really that much better than a healthy lunch. Fast food splurge = so not worth it.
